sidin [at Detroit, in the county of Wayne and gtate of Michigan, have invented'new and useful Improvements in Automatic Starters and Controllers, of which the folf lowin'gis a'specification. y'invention relates to improvements in electrica automatic starters and controllers, and it consistsin the combinations, construcarrangements herein described and claimed.

An object of my invention is to provide a device to beused in connection with gas, gasolene or oil driven electric generating sets, the purpose'bein to operate the said generating sets in such rent; at the proper voltage when there is a demand, forthe same, and to immediately generating of current when there is no demand for power.

A further object of my invention is to re-. duce and minimize the use of a storagebattryinconnection with the improved appamus, as distinguished from the present wellown practice of using heavy-duty or relatively powerful batteries in connection with electrical apparatus of thispharacterp In the present invention the batteryis relied upon only for current to start the motor or. generating system, and is cut-out or eliminated from the operating circuit as soon. as,

'established which is then lied with current direct from thelgen Thus a li ht-dut battery only, is required instead of ieavy-d iitybatteries as used in mg improvement. .It minrelative importance of the system as a whole and, thereat best more or. less ine'flici'ent and short serviee; 1 e improvement relative to tkeibattery savings in cost ="of construction, and; more especially in the cost of 'maintenance as heavy-duty batteries are err-- pensive. iniall respects as to first cost,. ma1n-' tenan'ce' r-replacement costs. s

My invention is illustrated in the accompanyin drawing, which is a diagralmnatic vlew o the varlous connectlons.

, In the practice of 'my invention, a generparts. and their circuit ator A is provided which may be a direct current, shunt,'or co ator of any suitable voltage. The enerator as here shown, is co nected direct y to and driven bya gasengine B, here shown for illustrative purposes gine. an engine of any suitable ca acity and type may be used in the system. in automatic or self-starter C is gearedv directly to the common shaft 1 of the starter, motor and generator, and a battery D is provided to furnishcurrent for starting the motor and The capacity of the here shown for inns;

It is a potential relay and operates at a few volts under normal work- 1n voltage, which in this case, is'about vo ts. ,Relay ,is a current-relay inseries with the generator.

The rela Z is a current relay in serieswith the switc S', the battery, and the 'mains L and'L", and is used to control the starting. circuit.

The auxiliary switch S is thus open during normal running, which gives relay Y nition circuit. The relay Z is protected from the enerator voltage b the openingof the auxiliary switch S. the auxiliary switch S closes the circuit between the starting motor-generator and the generator, to charge the battery in addition to furnishing current ior ignition and for operating the circuit breaker solenoid.

It will be seen that'the operation of the generating sets is controlled by the condition of the load on the circuit mains, and
